Native to Europe, North Africa, and Western Asia, Sweet Woodruff is a delightful groundcover with dainty baby-breath-like white flowers that blossom in the spring to early summer. It has a sweet scent and is a natural insect repellent making it a good companion for roses, peonies, hostas, bleeding hearts, columbines, and astilbes. It’s the perfect groundcover for those shady spots near trees or hedgebanks.
As an herb, Galium is sometimes used as a flavoring agent derived from coumarin! Mainly in Germany, it is used to flavor May wine (Maibowle) or punch that is drunk on the first of May. It is also used to flavor syrup for beer, brandy, sausages, jelly, jam, a soft drink, ice cream, and herbal tea. It is especially popular among young adults mixed with schnapps or vodka.
When dried, it can be used to enhance potpourri or like lavender, sweeten up your linen closet and drawers.
